Remarkable stability of tetrabenzo[,,,]fluorenyl ammonium salts in water: syntheses, reactions, and crystal structures

Deprotonation of 8b H -tetrabenzo[ a , c , g , i ]fluorene (8b H -Tbf), an extremely large benzannulated cyclopentadienyl derivative, by [NR 3 R′][OH] (R = n Bu, Et; R′ = n Bu, Et, Bn) leads to a series of Tbf ammonium salts of the type [NR 3 R′][Tbf]. These cyclopentadienide analogs were smoothly i...

Description
Summary:Deprotonation of 8b H -tetrabenzo[ a , c , g , i ]fluorene (8b H -Tbf), an extremely large benzannulated cyclopentadienyl derivative, by [NR 3 R′][OH] (R = n Bu, Et; R′ = n Bu, Et, Bn) leads to a series of Tbf ammonium salts of the type [NR 3 R′][Tbf]. These cyclopentadienide analogs were smoothly isolated from a hydrous medium and structurally characterized by single X-ray diffraction. Subsequent reactions demonstrate the high potential of derivatization by converting the presented [Tbf] anions into functionalized Tbf compounds.
